HON IN'G DEVICE.

To all whom it may concern:

Be it known that L'HAROLD F. ADAMS, a citizen of the United States,residing at Flushing, in the county of Queens and State of New York,have invented a new and useful Honing Device, of wlr'ch the following isa specification.

My invention relates to devices for honing cutlery, and it has for itsobject to provide a simple, inexpensive, convenient and efiective deviceto hold a knife blade at the proper angle when honing or whetting it.The pen knife is in almost universal use, yet few persons know theproper way to lay it on the stone when whet-ting it, or have the skillto hold it steadily at the proper angle while rubbing it over the stone;and as a consequence of such lack of knowledge and skill, the greatmajority of pocket knives usually have their edges in an unsatisfactorycondition. I have provided an extremely simple attachment by the use ofwhich even an inexperienced and unskilfu] person can whet his knifeproperly.

To the above ends, my invention consists in the device or attachmenthereinafter described and claimed.

In the accompanying drawings,

Figure 1 is an enlarged isometric view of my honing device, detached;

Fig. 2 is aside view of a pocket lmife having my honing device mountedon the blade thereof; and

Fig. 3 is an enlarged cross-section of a knife blade, with my devicemounted thereon and'lying on the hone or stone in position for whetting.I

My honing device 10, in the form here shown, consists of a strip ofspring metal, preferably steel, bent along its length into an open endedtube having such a form that the two edges of the strip come together,or approximately so, forming a slit 11 between said edges. The cornersmay be cut away at one or both ends, to form an entering notch 12. Whenthe device is to be used, the blade 13 of the lmife is inserted into orthrust lengthwise through the tube 10, with the back of the blade insidethe tube and the blade projecting through the slit 11, so that the edgeof the blade is outside of the tube, as shown in Figs. 2 and 3. Toinsert the blade, the point thereof is started in the notch 12, and thetube 10 is then forced lengthwise over the blade, which wedges itsSpecification of Letters Patent.

way into the slit 11. The tube is held on the blade by its ownresilience. 9

The tube 10 is of such form and size that, when said tube and the knifeblade are laid on a hone 14, as shown in Fig. 3, the blade will be heldat an angle suitable for honing. It will be understood that the form ofsaid tube can be varied. Said tube is shown of cylindrical form, whichis perhaps preferable as being the simplest and as being pleasing tohandle; but other forms can be employed, so long as the shape is such asto hold the back of the blade at a suitable elevation when laid on thehone.

It will be understood that-my attachment is not a handle by which tohold a blade to be sharpened, but is a guide to be mounted on a bladehaving its own handle 15.

The precise angle at which the blade will be held on the stone, willdepend upon the relation between the width of said blade and thediameter of the cylinder 10, if the tube is cylindrical; and, with anygiven tube, said angle will vary more or less with blades of differentwidths. A very wide blade will re quire a tube of greater diameter thana very narrow blade. I have found, however, that a single tube can beused with blades differing more or less in width without any seriousdeparture from good practice.

At least one end of the tube 10 is preferably beveled off, this beinaccomplished in the present instance by ma ing the notch at that end ofsuitable depth and shape to produce inclined edges 16. When the knifeblade to be sharpened has the tube is so placed on said blade as thatthe bevel or slant 16 bears approximately the same relation to thecurved part of the edge of the blade that the straight part of the tubedoes to the straight part of said edge. Said straight part of the edgeis whetted by laying the blade and tube fiat on the stone as shown inFig. 3, and the curved part of the edge is whetted by suitably tiltingthe knife up endwise, the angle between the blade and the stone beingdetermined by the bevel 16, which now rests against said stone.

In Fig. 2 the left hand end of the tube 10 is shown reaching entirely tothe end of the sharp part of the blade, but this is not necessary. Inother words, the tube can be shorter than shown.

It will be perceived that my honing ata rounded point, 7

tachment is very simple, and inexpensive, that it is convenient andeffective in operation, and is small and can be readily carried in thepocket or kept With the hone ready for use When needed.

Having thus described my invention, what I claim as my invention anddesire to secure by Letters Patent is:

A honing attachment for knife blades having curved ends, said attachmentconsisting of a tube having a straight part with a longitudinal slit forthe purpose set forth,

Copies of this patent may be obtained for and said tube being beveledoff at one end on opposite sides of said slit to guide the blade tocontrol the honing of said curved end of said blade, the guiding portionof the beveled end of the tube being spaced from the curved end of theblade to give substantially the same angle on the hone as the straightportion.

In testimony whereof, I have hereunto affixed my signature.
